SPK series lifting furnace is a new type of electric furnace independently developed and produced by SPK company. It introduces advanced technology, has advanced and reasonable structure, beautiful and generous appearance. The shell is made of cold-rolled steel plate, processed by advanced CNC machine tool, luxurious and beautiful two-color epoxy powder electrostatic spray molding process, and is resistant to high temperature and corrosion. It uses excellent heating elements. The double-layer furnace shell is equipped with an air cooling system, which can quickly cool down; The furnace has the advantages of balanced temperature field, low surface temperature of furnace body, fast temperature rise and fall rate, and energy saving.
The lifting furnace is applicable to all kinds of small parts, springs and moulds for heat treatment without oxidation and decarburization. It is also suitable for universities, scientific research institutes, industrial and mining enterprises to do powder baking, ceramic sintering, high temperature experiments, chemical analysis, material processing, quality testing and other metal parts heat treatment.
